Our Observations
With Hikmicro Owl OH-25, the user has to long-press the on/off button for 3 seconds until the manufacturer’s logo appears. After the logo disappears, we get the image, and the Start up timer stops. Next, the device calibrates, and soon after the icons appear in the top right corner. That’s when the device is ready to be used (as it enables all features) and the second timer stops.
You can press the zoom button before the device is ready, but it starts working when the display icons appear. The number of times we press the zoom button does not matter; a singular button press is enough for the device to zoom in once it’s ready for use. This is why we pressed the zoom button in longer intervals.
As the manufacturer states, Hikmicro Owl OH-25 has a built-in, simple-to-charge battery.
The device is easy to handle, and the buttons are easy to press even if you are wearing gloves.
Hikmicro states that the device turns on in under 5 seconds. However, this does not include the first 3 seconds during which the user must hold the on/off button until the logo appears. When measuring the time from the moment your finger presses the button and up to the part where the image appears, we can see that the actual start up time is approximately 6.44 seconds.
When the screen first turns on, the device is unresponsive to the user’s actions. For that reason, we also measured the “Ready to use time”, which is the period between the press of the on/off button and the point where the device starts responding to the user’s actions. You can detect when the device calibrates, as it also produces a click noise. Soon after, the icons appear, and the device, along with all functions available, is ready to be used.
Hikmicro Owl OH-25 has a Standby option, which is a remarkably useful battery-saving feature. With the press of the on/off button, the screen turns off and the device enters the Standby mode. To use the device again, you simply press the on/off button.
